Restoration at the Hedrick Ranch Nature Area FWS Agreement Number 81440-05-G-016

The goal of the Hedrick Ranch Nature Area (HRNA) Restoration Project was to restore natural function to

riparian and wetland habitats historically found along the Santa Clara River. The project included the removal

of invasive, non-native plants and revegetation with native plants. Funding for this project was provided by the

U.S. Fish and Wildlife Service (FWS) from settlement claims for natural resource damages resulting from an

ARCO pipeline oil spill into the Santa Clara River.

The HRNA is a 220+ acre property located east of the city of Santa Paula, along the south side of the Santa

Clara River just north of South Mountain Road (denoted in red on Figure 1, below). The property is owned by

the non-profit Friends of the Santa Clara River (FSCR). HRNA was the first acquisition under the Santa Clara

River Parkway Project, a program begun by the State Coastal Conservancy with the goal of eventually creating

a 6,000-acre protected riparian corridor extending from Fillmore to the ocean.

PROJECT DESCRIPTION

This restoration project focused on ~48 acres of the Hedrick Ranch Nature Area (HRNA). A planting plan was

designed with the goals of enhancing wildlife functions and values and eradication of invasive non-native

weeds. These goals were achieved through the combined effects of weed removal and the installation of native

plants and seeds, using both volunteer and paid labor. The volunteer base developed through a separate but

related FWS grant (G-015) assisted with restoration. Work on this restoration grant (G-016) began in

December 2004 and was completed in May 2011.

Key elements of the habitat restoration activities included:

1. Revegetation of riparian terrace habitats

2. Enhancement of wetland habitats to increase species diversity

3. Removal of priority invasive, non-native plant species throughout riparian terrace and wetland habitats

4. Monitoring and maintenance of invasive plant removal and revegetation.

Hedrick Ranch Nature Area Restoration Project Final Report


BACKGROUND

Historic uses of the land now within the Hedrick Ranch Nature Area were livestock (cattle and horse) grazing,

orchards including walnuts and citrus, and row crops such as lima beans, sugar beets, alfalfa, and watercress.

When volunteers began the initial restoration work of weed removal in 2002 (without any funding), the crops

had been removed but the property was still grazed by cattle and horses. The first step in the restoration process

was to remove all livestock grazing; however, once the livestock was removed, the pastures became choked

with head-high thistles, fennel, various mustards, and non-native grasses, and became surrounded by dense

arundo and castor bean. The small group of volunteers organized by Sandy Hedrick went to work removing

weeds by hand and installing pole cuttings of willow, cottonwood and sycamore.

Prior to restoration, wildlife habitat and niche selection were extremely limited due to the very low diversity of

plant species and communities and ongoing agricultural activities. Wildlife use was restricted to common

species tolerant of such land uses. A key measure of restoration success is species richness, as documented

through field surveys. Although no quantitative data on flora and fauna was collected, qualitative species lists

for the entire HRNA property were recorded beginning in 2002 (URS, 2003), with informal plant and wildlife

(particularly bird) lists collated by individuals for many years prior.

These data along with more formal surveys conducted over the years have been used in the report to provide a

qualitative discussion of relative habitat restoration success. Professional wildlife surveys were conducted in

2008, 2010 and 2011 by Jim Greaves, John Griffith, and the Western Foundation of Vertebrate Zoology (Linnea

Hall, et. al.). Professional botanic surveys have been ongoing since project initiation, by Coastal Restoration

Consultants (Dave Hubbard and Matt James). Many HRNA volunteers are flora and/or fauna experts, and have

contributed substantially to the comprehensive species lists provided in the appendices.

RESULTS & DISCUSSION

Enhancement of Wildlife Functions and Values

Restoration efforts focused on increasing the complexity of habitat structure to provide greater ecosystem

opportunities for wildlife, both between and within habitats. This was achieved in part through establishing

diverse vertical habitats by planting a variety of trees and shrubs, by creating both permanent and temporary

surface water elements to support aquatic and wetland plants and wildlife, including shorebirds and other

migratory waterfowl, and by including open habitat areas such as perennial grasslands. A wide variety of birds,

butterflies and other insects, mammals, and reptiles are now utilizing the restored habitats of the HRNA, as

illustrated by the wildlife occurrence lists provided in Appendix A and B.

Thirty-one species of native plants were installed to improve vertical and lateral wildlife habitat via greatly

increased habitat diversity. The locations chosen for planting were based on relative value to enhance habitat

value and to control weeds. Understory and groundcover species were used within willow woodlands as well as

in areas were weeds had been removed. These plants included yerba mansa, mugwort, beggars tick, field sedge,

saltgrass, western goldenrod, spiny rush, rushes, spikerush, alkali rye grass, deergrass, and California

blackberry. In the shrub layer, species planted included quailbush, Mexican elderberry, giant ryegrass, and

sandbar willow. Tree species comprised southern California black walnut, black cottonwood, western

sycamore, coast live oak, and arroyo willow.



Plants installed on-site were purchased from a local native plant nursery (Matilija Nursery) or grown at the on-

site nursery. All propagation materials collected for site-grown plants and pole cuttings came from the HRNA

and plants from Matilija Nursery originated within the Santa Clara River watershed. Plant diversity within the

focus area for this grant was extremely low at the beginning of the project, with the majority of propagules

derived from elsewhere within the HRNA.

Tree growth was the most important naturally-occurring change at the site. Willows and mulefat recruited to

the site in high densities after flooding during the winter of 2005 covered large portions of the HRNA with a

thick layer of silt. This resulted in dense monocultures of arroyo willow and mulefat, to the exclusion of other

species. Dense leaf litter further reduced the natural occurrence of plants, controlling the growth of both native

plants and weeds. Over time, some natural thinning of the willows occurred. The restoration team selectively

removed smaller diameter willows and mulefat, and interspersed native plants.

Formal wildlife surveys were conducted for this project by professional biologists since 2008.1 Focused

surveys for least Bell’s vireo were conducted in 2008 and 2010, general breeding bird surveys in 2010, and in

2011, both breeding bird and comprehensive wildlife surveys were completed. Appendix A and B provide a

comprehensive list of all wildlife sighted at HRNA since work began in 2002.

Over 190 species of birds have now been identified on HRNA, including the endangered least Bell’s vireo

which regularly nest at the HRNA each year, and southwestern willow flycatcher. {In 2010, focused least

Bell’s vireo surveys found 74 occupied sites, including 71 pairs and 3 single males. Eight nests were located

for six pairs, and all 6 pairs were successful with 23 fledglings produced and 14 post-fledging family groups

containing 48 fledglings observed.} The federally-listed endangered yellow-billed cuckoo was recorded in June

2011, a new record for HRNA. Species listed by the California Department of Fish and Game as Species of

Special Concern found on-site include white-tailed kite, northern harrier, yellow warbler, and yellow-breasted

chat. In comparison, surveys conducted in 2002 found 73 species with 35 breeding. There are now 69 species

breeding.

At least 14 mammal species are known to utilize the property comprise mountain lion, bobcat, coyote, and

raccoon. Butterfly and moth species noted consist of west coast sister, monarch, anise swallowtail, west coast

ladies, Lorquin’s admiral, and many others, totaling 24 species. Nineteen herps (amphibians and reptiles) have

been identified, including pacific chorus frog, gopher snake, rattlesnake, kingsnake, pond turtle, and lizards.

Surveys in 2002 found three mammal and two reptile species.2

Key achievements are summarized below:

Vegetation enhancement was conducted utilizing purchased and site-grown native species.

Plants were propagated on-site comprising 31 species.3 All plants were derived from seeds, cuttings or

other propagules collected on HRNA or in the watershed.

Plants were purchased from a local native plant nursery. Volunteer groups installed these plants.

Three new wildlife ponds were constructed (under a separate grant) and a fourth pond was enhanced; all

four were planted with native species.

1 Least Bell’s vireo surveys conducted by Jim Greaves (2008) and John Griffith (2010); general bird and wildlife surveys conducted

by the Western Foundation of Vertebrate Zoology led by Linnea Hall (2010 bird only; 2011 wildlife); butterfly & moth informal

survey led by Professor Walter Sakai (June 2011). 2 It should be noted that most wildlife surveys were conducted over the entire ~220 acres and were not focused on the 48 acres

covered under this grant funding. The exception is the butterfly & moth survey, which covered a very small portion of the HRNA. 3 The plant nursery was created on HRNA under another grant.



Weed Eradication

The restoration work was conducted by Friends of the Santa Clara River and volunteers, with contractors hired

for the targeted removal of giant reed, castor bean, poison hemlock, pepperweed and invasive grasses (primarily

tall fescue and tall wheat grass). Contractors used a variety of approaches, such as mowing with specialized

equipment and standard lawn mowers, hand cutting with chain saws and machetes, and herbicide treatment.

Giant reed was specially treated by hand cutting immediately followed by swabbing or painting of contact

herbicide. Volunteers focused on hand removal of thistles, mustards, wild radish, sweet clover, pepperweed and

other invasive non-natives.

Significant progress has been achieved in the removal of invasive non-native plant species, with substantial

control of thistles, castor bean, mustards, sweet clover and perennial tall fescue. As native plant species

continue to become established, natural weed suppression has increased. Many of the native species chosen for

restoration were selected both for their wildlife habitat values and their ability to out-compete weeds. Examples

of species used for weed control included quail bush, giant rye, and deergrass. These plants grow quickly and

cover large surface areas, thus suppressing weed growth through direct competition for light and nutrients. An

added benefit of these particular plants is their high wildlife value, providing food, shelter and nesting habitat

for birds, small mammals, herps and many insects.

Key achievements are listed below:

Giant reed (Arundo donax) was removed within a 14-acre segment along the south bank of the Santa

Clara River.

Weed control:

o Intense weed control (mowing & herbicide treatment) in the vicinity of Flycatcher Ditch (South

Pasture) and North Pasture (area adjacent to bioswale site).

o Invasive control over entire site, using hand weeding

List 4: Plants of Limited Distribution - A Watch list. Includes Rare Plant Rank 4.1, 4.2, 4.3

Plants in this category are of limited distribution or infrequent throughout a broader area in California, and their vulnerability or susceptibility to threat appears low at this time.

While we cannot call these plants “rare” from a statewide perspective, they are uncommon enough that their status should be monitored regularly. endangerment
